I put my wireless thermostat directly above the hall radiator,
she still hasn't worked out why she cant control the house temperature with the thermostat. If I am cold I just turn off the hall radiator

Even my six inch nail hammered through the thermostat jamming it at 20 deg C didn't work or any other combination of dummy stats or lectures of reason. In the end I cancelled my standing order with BG and put it into STHTBO's name and her account number. She can twiddle it to her hearts content now and my blood pressure has dropped considerably knowing it's coming out of her account.

My new years resolution is to try and get the kids mobile phones bill onto the same account, as they too don't seem to get the logic of keeping to an inclusive tariff.
